Air-to-air missile versions There are currently four main variants of AMRAAM, all in service with the
United States Air Force,
United States Navy, and the United States Marine Corps.
AIM-120A AIM-120A is no longer in production and shares the enlarged wings and fins with the successor, the AIM-120B.
AIM-120B AIM-120B deliveries began in 1994. This variant had improved electronics, including a digital processor, upgraded memory, and electronic unit hardware chassis upgrades.
AIM-120C AIM-120C deliveries began in 1996. The C-variant has been steadily upgraded since it was introduced. The AIM-120C has smaller "clipped" aerosurfaces to enable increased internal carriage on the
USAF F-22 Raptor from four to six AMRAAMs. The AIM-120C-5 and above have an improved HOBs (High Off Bore-Sight) capability which improves its G overload and seekers field of view over the previous variants. This allows the missile to be more maneuverable and be used against targets that are offset from the launching aircraft frontal view which allows for greater flexibility during air-to-air combat. The AIM-120C-6 contained an improved fuze (Target Detection Device) compared to its predecessor. The AIM-120C-7 development began in 1998 and included improvements in homing and greater range (actual amount of improvement unspecified). The AIM-120C-7 also featured another compression of the flight control system shortening it by roughly 15 cm. According to Air Combat Command Public Affairs, starting with the AIM-120C-7, the AIM-120 series received an enhanced motor with an additional 5 inches of propellant (referred to as the +5 rocket motor). It is unspecified for how long this extends the burn time of the motor. It was successfully tested in 2003 and is currently being produced for both domestic and foreign customers. It helped the
U.S. Navy replace the F-14 Tomcats with F/A-18E/F Super Hornets – the loss of the F-14's long-range AIM-54 Phoenix missiles (already retired) is offset with a longer-range AMRAAM-D. The lighter weight of the enhanced AMRAAM enables an F/A-18E/F pilot greater bring-back weight upon carrier landings.
FMRAAM The FMRAAM (Future Medium Range Air to Air Missile) was a modified ramjet powered version of the AMRAAM that was conceived during the mid-1990s to fulfill British requirements for a new longer range missile on their new Eurofighter Typhoon fighter. The FMRAAM was to use the
Aérospatiale liquid fueled
RASCAL (Ramjet for Small Calibre) propulsion system. It competed with and lost to the
MBDA Meteor, thus never reaching production. Work on a ramjet motor for the AMRAAM continued under the Variable Flow Ducted Rocket - Flight Vehicle Concept (VFDR-FVC) program in the 2000s, with a prototype demonstrator tested by Aerojet by 2008.
AIM-120D AIM-120D is an upgraded version of the AMRAAM with improvements in almost all areas, including 50% greater range (than the already-extended range AIM-120C-7) and better guidance over its entire flight envelope yielding an improved kill probability (
Pk). Initial production began in 2006 under the Engineering and Manufacturing Development phase of program testing and ceased in September 2009. Raytheon began testing the D model on August 5, 2008, the company reported that an AIM-120D launched from an F/A-18F Super Hornet passed within lethal distance of a QF-4 target drone at the
White Sands Missile Range. The range of the AIM-120D is classified, but is thought to extend to about or potentially up to . The AIM120D after F3R (Form, Fit, Function, Refresh) has a slightly bigger motor section. A more efficient battery and coding gives the AIM-120D increased range according to Raytheon Vice President Jon Norman. The AIM-120D (P3I Phase 4) is a development of the AIM-120C with a two-way data link, more accurate navigation using a GPS-enhanced IMU, an expanded no-escape envelope, and a max speed of Mach 4. The AIM-120D is a joint USAF/USN project for which Follow-on Operational Test and Evaluation (FOT&E) was completed in 2014. The USN was scheduled to field it from 2014, and AIM-120D will be carried by all Pacific carrier groups by 2020, although the
2013 sequestration cuts could push back this later date to 2022. The
Royal Australian Air Force requested 450 AIM-120D missiles, which would make it the first foreign operator of the missile. The procurement, approved by the US Government in April 2016, will cost $1.1 billion and will be integrated for use on the F/A-18F Super Hornet, EA-18G Growler and the F-35 Lightning II aircraft. There were also plans for
Raytheon to develop a
ramjet-powered derivative of the AMRAAM, the Future Medium Range Air-Air Missile (
FMRAAM). The FMRAAM was not produced since the target market, the British Ministry of Defence, chose the
Meteor missile over the FMRAAM for a
BVR missile for the
Eurofighter Typhoon aircraft. Raytheon is also working with the
Missile Defense Agency to develop the
Network Centric Airborne Defense Element (NCADE), an anti-ballistic missile derived from the AIM-120. This weapon will be equipped with a
ramjet engine and an
infrared homing seeker derived from the
Sidewinder missile. In place of a
proximity-fuzed warhead, the NCADE will use a
kinetic energy hit-to-kill vehicle based on the one used in the Navy's
RIM-161 Standard Missile 3. The -120A and -120B models are currently nearing the end of their service life while the -120D variant achieved initial operational capability in 2015. AMRAAM was due to be replaced by the
USAF, the
U.S. Navy, and the
U.S. Marine Corps after 2020 by the Joint Dual Role Air Dominance Missile (
Next Generation Missile), but it was terminated in the 2013 budget plan. Exploratory work was started in 2017 on a replacement called
Long-Range Engagement Weapon. In 2017, work on the
AIM-260 Joint Advanced Tactical Missile (JATM) began to create a longer-ranged replacement for the AMRAAM to contend with foreign weapons like the Chinese
PL-15. Flight tests are planned to begin in 2021 and initial operational capability is slated for 2022, facilitating the end of AMRAAM production by 2026. In July 2022, Raytheon announced the AIM-120D-3 became the longest-range variant in testing, as well as an air-launched adaptation of the NASAMS-based AMRAAM-ER called the
AMRAAM-AXE (air-launched extended envelope). The development of AIM-120D-3 and AMRAAM-AXE is likely driven by the PL-15 performance. The AIM-120D-3 and the AIM-120C-8 variant for international customers were developed under the Form, Fit, Function Refresh (F3R) program and feature 15 upgraded circuit cards in the missile guidance section and the capability to continuously upgrade future software enhancements.
Ground-launched systems on HMMWV The
Norwegian Advanced Surface-to-Air Missile System (NASAMS), developed by
Kongsberg Defence & Aerospace and fielded in 1994–1995, consists of a number of towed batteries (containing six AMRAAM launching canisters with integrated launching rails) along with separate radar trucks and control station vehicles. The US Marine Corps and the US Army tested launching AMRAAM missiles from a six-rail carrier on
HMMWV as part of their CLAWS (Complementary Low-Altitude Weapon System) and
SLAMRAAM (Surface Launched AMRAAM) programs, which were canceled due to budgetary cuts. A more recent version is the
High Mobility Launcher for the NASAMS, made in cooperation with
Raytheon (Kongsberg Defence & Aerospace was already a subcontractor on the SLAMRAAM system), where the launch-vehicle is a Humvee (M1152A1 HMMWV), containing four AMRAAMs and two optional
AIM-9X Sidewinder missiles.
AMRAAM-ER As part of the SLAMRAAM project, Raytheon offered the Extended Range upgrade to surface-launched AMRAAM, called AMRAAM-ER. The missile is an
Evolved Sea Sparrow Missile using AMRAAM head with two-stage guidance system. It was first shown at the
Paris Air Show 2007 and was test-fired in 2008. Following the cancellation of SLAMRAAM funding in 2011, development of the NASAMS version restarted in 2014. In February 2015 Raytheon announced the AMRAAM-ER missile option for NASAMS, with expected production in 2019, and the first flight test took place in August 2016. Engagement envelope was expanded with a 50 percent increase in maximum range and 70 percent increase in maximum altitude. In 2019
Qatar placed an order for AMRAAM-ER missiles as part of a NASAMS purchase. The missile was testfired at
Andøya Space Center in May 2021. In February 2024, Raytheon flight-tested an upgraded version of AMRAAM-ER with an improved rocket motor and control actuator system and an AIM-120C-8 guidance head. Raytheon has proposed an air-launched adaptation of the missile called AMRAAM-AXE, from "Air-launched Extended Envelope". ==Foreign sales==
